I admit I messed up commit 0467a78f9efd89e7c17a1eaffd8b1928291834c7 in a few ways: * I parsed numbers in the selection expression as friend tree specifiers   by accident, of course this was easy to fix. * And the written TTree/TChain copies where messed up as soon as the   'autofriend' feature was involved. This has been due to the reason that   TTree::CopyTree() also copies the list of friends even though these are of no   use for the copy, since the number of entries does not match anymore. * Also this part might have improved on readability.
